[gentoo-amd64] Kernel-3.10 Nvidia Emerge Failure And Other Stuff

[Frank Peters <frank.peters@comcast.net>]

Kernel-3.10 has just been released and I quickly grabbed the source
and compiled.  I usually have no problems with a new kernel but this
time there were a few surprises.

First, there is a new kernel option called "Kernel support for scripts
starting with #!."  This option seemed applicable only to boot scenarios
involving initramfs but unchecking it caused my system to fail to boot.
Because this may cause unexpected problems for others, I mention it here.

Second, the RTC (real time clock) module option, which has been present
for a long time as a basic kernel driver, has suddenly disappeared.  To
get the same functionality, one has to enable the new "PC-style CMOS"
RTC driver, and because this builds a module with a different name (rtc-cmos
vs. rtc) my custom start-up scripts suddenly were broken.  It took a bit
of searching to resolve the problem.  I suppose that users of udev may
not notice the change, but I mention it just in case others may  experience
something similar.

However, the main problem for me with kernel-3.20 is that the nvidia-drivers
will fail to emerge.  Here is the error:

nvidia-drivers-319.32/work/kernel/nv-i2c.c: In function 'nv_i2c_del_adapter':
nv-i2c.c:327:14: error: void value not ignored as it ought to be

When I encountered this failure I expected that a huge outcry of bug reports
would ensue, but so far things have been rather quiet.  There are only a few
postings of this problem with 3.10-rc1 and not much else.

I should perhaps just patiently wait for the eventual rapid fix, because this
error is a real show stopper, but I will make an inquiry nonetheless.
Has anyone on the list encountered this error with nvidia and kernel-3.10?

I hope it is not, again, some strange affliction peculiar to my machine.
